TYPEWRITING BIACHINE.

Application filed November 13, 1919.

To all whom it may concern:

ie it known that I, {i nssn A. B. SMITH, a citizen of the United States, residing in Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and use ful Improvements in Typewriting Machines, of which the following is a specification.

This invention relates to typewriting machines, and is herein disclosed as applied to an Underwood typewriting machine of the type known as the continuous fan-fold billin machine.

n using such machines, as well as other ty ties of machines, for the making out of bills, with the simultaneous typing of carbon copies of the bills, certain difficulties arise in making the bills attractive and neat, inasn'iurh as the hills hitherto used have usually been t -yped upon continuous fanfolded webs, which were afterwards sevcred longitudinally and transversely. lVhere a 'lan-folded web of this type was employed, the plies of web were necessarily all of the same kind of aper, which, from motives of QL'UIIOIIIY, was usually a rather low grade of paper, frequently presenting a rather unattractive appearance, especially if much handled.

According to the present invention, many of the advantages of such machines may be preserved, and yet the bill may be typed upon any desired kind or size of work-sheet or bill head, while the typed carbon copies are made out simultaneously upon the usual web, which may he severed as desired.

In obtaining these and other advantages, I have found it advantageous to use a plate or gage, which normally may form a collating table or part of a collating table, but which is adapted to be swung away from its normal position to permit a bill head or other work-sheet to be inserted behind it and be guided by it down in front of the platen.

This device is especially useful when it is em 'iloyeiil in connection with the continuous fan-fold billei' described above, one

form of which is shown in the patent to \Vernery & Smith, No. 1,132,055, dated Serial No. 337,733.

and the webs which lie beneath the platen may he pulled upwardly behind the gage or platen, so that the bill head or work-sheet is readily inserted behind the plate and in front of the webs and carbon sheets, and slides down behind the usual knife, which is shown in the patent to Jesse A. B. Smith, No. 1,237,716, dated August 21, 1911.7, and thence around beneath the platen. Both the ends of the webs and the top of the bill head may be aligned against the gage or plate, and held gaged while the swing frame is swung rearwardly to carry the platen against the feed-rolls. Then the platen may be rotated backwardly to bring the desired line upon the bill head to the printing point, and the typing proceeds as usual. When the typing is finished the platen may be swung upwardly in the usual manner, the carbon sheets pushed rearwardly, the bill head removed, and then the platen frame swung back and the webs severed against the knife.

lVhen used with the \Veinery and Smith structure, the plate or gage may sometimes be fixed in front of the usual front paper table. thr rendering it unnecessary to swing the gage clear of the table.

Other features and. advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a sectional side view, largely diagrammatic, of an Underwood standard typewritingmachine of the kind referred to.

Figure 2 is a similar view, showing the platen lifted and the bill head and Worksheets being aligned.

Figure 3 is a perspective view of the collating table and the gage or plate thereon.

In the Underwood fan-fold continuous billing machine, webs 1 are drawn forwardly over the rear bar 2 of an extension 3 of the typewriter carriage L, and, passing over a bar 5, bend downwardly around the platen 6 and are carried to the printing point at the type 7, diagrammatically shown in Figure 1. The webs 1 are held against the platon by feed-rolls 8 and 9 and an apron 10, beneath the platen 6, and bend rearwardly above the printing line beneath a knife 11, lying near the platen above the printing line. The feed-rolls may be moved to their outer dotted line positions by the usual means.

was

in order to maize carbon copies upon the webs l of matter typed upon an outside work-sheet or bill head 12, there are provided carbon sheets 13, wh'ch are clipped to the bars 14 of the usual carbon carriage 15 of the Undeiwood tan-told billing machine. The carbon paper carriage 15 runs upon rails 16, forming part oi? the extension ll hen all the matter to be typed bill head 12 has been typed, the liaviiigg been advanced by tne usual. lever, not shown, the typist presses 3 a linger-piece 1'? to release a hook lb, which normally holds a swing frame 1' in which the platen is iournaled by its ainc 19 so that the platen rests against the leed-rolls 8 The typist then s Blilih anie forwardly upon t" "t 20 on which it is journaled, usually Jlle tl'rame until an upper extension adjustable end gage J-Q T .1. the t ypist ving' is.

thereoit having an This permits E2. horizontal.

to raw th we s together with the carbon sh: 123 to rdiy practically straight ber e platen, and gage the webs against the e 22, the typist, according to the pres lTlYGHtlOD also usually holding the worksheet 12 against the extension 21. Then the typ'ist usually pushes rearwardly a handle forming part oi the carriage 15, thus pushing; the carbon sheets 13 rearwardly between the wor {-sheet 12 andwebs 1 until the 'lront ends ol? the carbon sheets are. behind the knife 1 1.

The typist then usually s "ings the swing frame 18 rearmirdly, so that it is again caught by the hooks l8, and, according to the present invention. usually removes the work-sheet 12 and then severs the webs l by drawing; them against the edge of the knife 11; This leaves the webs l a little lower than the point seen in Figure l, and also leaves the carbon sheets 13 a little lower both as measured at the knife 11. Then it a swinging gage 2a is used, which forms a guide-plate erected the front of the platen. the typist draws the plate or gage E24.- upwardly and forwardly, "from a rearwardly inclined to a forwardly inclined position, around its pivots 25, by which its 26 are pivoted upon the side pieces 27 of the swing frame 18. The gage Q l may be provided with a handle 28 to permit it to be swung, and may also be provided with a de tent or boss 29 adapted to catch in an opening or depression 30 to hold it so swung loi ardly, its new position being shown in the broken linesot Figure l. in which beveled lower edge lies just behind the indie 11. Then the typist advances the webs l and carbon sheets by rotating the platen.

Then the typist seizes an unused worl-sheet or bill head and passes it down between the out side carbon 1.3 and the back of the plate 2 1, seen in Figure 2, and gages the bill head 12 and, if desir d, in addition, the ends ol? the webs l against the top edge of an upper extension oi the plate 2%, which thus 1" orins a leading edge gage, while the knife 11 and apron 10 form a chute for guiding the bottom oi? the work-sheet 12 rearwardly. Next the typist, while holding the webs and worksheet 12 thus gagged swings the swing frame 18 rearwardly, bringing the platen 6 against the reed-rolls S and 9, thus holding the webs l and work-sheet 12 properly aligned. To bring the work-sheet 12 and webs 1 to the proper writing line, the platen may be rotated rearwardly to bring thenn say to the Figure l position at which position the plate or gage may be swung rearwardly to lie upon the table 31, and may itsell serve as a table for the advancing webs and work-sheet in the ensuing typing operation. When the typing is completed. the webs are advanced and severed as described above.

The plate or gage 2st may be normally detained against the table 251 by an. opening or depression which is adapted to cooperate with the boss 29 in the normal posi tion of the plate 24. he plate may be formed as an integral structure ot light metal, and have its arms or ears 26 integral therewith. The pivots 25 on which the ears 2b swing are advantageously a little above and in front of the bearings oi the platen axle 19, *ith the result that the lower end ot' the plate 2 1 in its Figure 2 position lies just below and back of the top of the knife 11, thus ma 1;; it impossible for the bill head to catch. upon the knife while sliding down., while the knife cooperates with the plate 24: to guide the bill head.

it will be noted that bill head 12 may be of any desired quality oi paper. and the webs 1 may be oi? any other desired quality, thus rei'ii ering it possible to use fine lithographed bill head to advantage with as cheap or as expensive :1 record web as may be de sired. The plate at may he ot a size suitable tor the standard sizes of bill heads and the in be fiCljllStGt. to give any desired b ank s ace between copies of sue cessive bills. my .ny desired allowance scope of the invention, and portions of the it, of a collating plate normally lying upon said table, a printing instrumentality in front of the platen, and a support for said plate on which it can be swung from the table to a position where it will guide behind said printing instrumentality a worksheet inserted behind it from above.
